光电编码器在分光计中的应用

Application of photoelectric encoder in spectrometer

用精密角度传感器代替了分光计原来的机械读数盘,通过数字显示器显示传感器感应望远镜角度变化的电信号,实现了分光计数字化读数,并设计了安装传感器时消除偏心差的调整方案.改造后的分光计读数快捷方便,且其测量精度也得到提高.

The original mechanical reading dial of spectrometer was replace with high-precision angular transducer.Digitized angular change sensed by the transducer of the telescope was shown directly on the digital displayer,which realized the digital reading of the spectrometer.Meanwhile,an adjustable scheme used to eliminate the eccentric difference during the installation of the transducer was designed.The modified spectrometer could not only realize quick and easy angular reading but also improve the precision to a large extent.
